Heil HG Series 10 unit
We purchased a building in 2008 that had a Heil HG Series 10 unit on the roof.
This past year with our hot weather the HVACs unit started popping the circuit breaker in the electrical panel inside.
We have replaced the breakers, cleaned the ac unit and now we need to find out what kind of warranty we have if it continues to pop the breakers.
How can we tell from our S/N?
